ATTACK ON NETWORK SECURITY

There are basically three types of attacks-
1) Reconnaissance attack- This attack basically deals with the information gathering which is later used to compromise the network. This type of attack includes- Packet sniffing, Port scan, Ping sweeps etc.

2) Access attacks- This attack is done when the vulnerability in the network is found in 1st stage. this attack includes-IP spoofing, password cracking(Brute force attack, Dictionary attack), Man in middle attack(Session Hijacking), Server Spoofing, Trust exploitation, Buffer overflow.

3)Denial of Service(DoS) attack- • DoS attacks prevent access to part or all of a computer system. They are usually achieved by sending large amounts of jumbled or otherwise unmanageable data to a machine that is connected to a corporate network or the Internet, blocking legitimate traffic from getting through. Even more malicious is a Distributed Denial of Service attack (DDoS) in which the attacker compromises multiple machines or hosts. Ex- ping broadcast, Ping of death, smurf, teardrop.
